The afternoon rush hour traffic heading north on 423 our of The Colony into Frisco/Little Elm has gotten much worse over the last couple of weeks. It is now consistently backed up from The Colony all the way to the Y intersection north of four corners. It seems like the traffic light at the 423/720 Y intersection has been retimed, which has resulted in traffic being backed up all the way to the four corners light. Sorry for the long post, but is there any hope for relief? Thanks.
